IPC: G06F19/00
Filed: 1983-12-26
Abstract: PURPOSE:To meet the delivery date and allow the work schedule to be changed in response to the work progress by determining the production work sequence at each work station centering the neck work station where the maximum load is detected. CONSTITUTION:Work direction units 2-1-2-4 calculate the production speed of individual work stations and report to a speed monitor unit 1 and also eliminate interferences at the predetermined priority when specified as the work direction unit of the neck process. When the schedule is advanced, the work direction unit of the preceeding process is reported; and likewise when the schedule is delayed, the work direction unit of the succeeding process is reported; thus the like process is repeated to update the work schedule. When the neck process exceeds the preset schedule period or mechanical interferences of each work station are eliminated, the process is completed. Accordingly, the speed is controlled and the schedule is changed centering the neck process, thereby a delay of the delivery date does not occur.
